There is no doubt that without nitrogen (or other inert gas), many more people would be killed by fire or explosion. Nevertheless, a heavy price has been paid for the benefits of nitrogen. Many people have been asphyxiated by it. Some accidents have been described in which people were ...
The first quantified the transfer of nitrous oxide, over time, in 19 female patients undergoing laparoscopy. The second established the lower limits of flammability of a range of concentrations of methane and hydrogen diluted with nitrogen (simulated bowel gas) in a range of concentrations of ...
The component content of gases from potash salt deposits is a complex mixture of combustible and inert gases, including nitrogen, methane, hydrogen, and methane-series hydrocarbons [16,23]. In general, the geographical distribution of the presented research indicates that the main results were ...
Physical hazards - like extreme temperature or radiation from UV light or radon gas Chemical hazards - like nitrogen dioxide (NO2) from air pollution or lead (Pb) from old water pipes Biological hazards - like bacteria, viruses, fungi, plants or animals ...
(to avoid contaminating groundwater with excess nitrogen or phosphorus) and prohibit spraying swine waste on already-saturated ground to avoid runoff. Under those permit conditions, spraying down lagoon levels may not be possible for some period time after the storm has ended because surrounding ...
Typically, the oxygen is displaced by a nitrogen blanket. Inerting is only possible in enclosed spaces, and is usually only found in certain processes. Inerting is not the safest way to remove flammable hazards, because a sudden inrush of air into the enclosed space will provide the oxygen ...
Nitrogen (N) variability can have a negative impact on many production practices as well as having a negative influence on the environment. Nitrogen can be... J Lofton,DC Weindorf,B Haggard,... - 《Agricultural Journal》 被引量: 14发表: 2010年 Scientific Opinion on Review of the European ...
It, therefore, undergoes a liquefication process, so that much higher quantities of fuel (approximately 600 times as much) can be stored and transported. For this to happen, the gas must be cooled to -162C/-265F within containers and pipes that are cooled using nitrogen. The liquefied gas...
Figure 1: Applications of Chloroacetonitrile Under a nitrogen atmosphere, Chloroacetonitrile (1 mmol), water (3 mL), and a ruthenium(II) complex (0.011 g, 0.02 mmol; 2 mol%) are introduced into a sealed tube, followed by stirring the reaction mixture at 40°C for 1 hour. The reaction ...
AE Germeles,EM Drake - 《Liquefied Natural Gas》 被引量: 9发表: 1975年 Electric breakdown of perfluorocarbon vapors and their mixtures with nitrogen This investigation was concerned with a study of the breakdown behavior of the higher molecular weight perfluorocarbon vapors and mixtures of these ...
